BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive soybean cultivar,designated 02340134. All publications cited in this application areherein incorporated by reference.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single cultivar animproved combination of desirable traits from the parental germplasm.These important traits may include, but are not limited to, higher seedyield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, altered fatty acid profile, abioticstress tolerance, improvements in compositional traits, and betteragronomic quality.

These processes, which lead to the final step of marketing anddistribution, can take from six to twelve years from the time the firstcross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

Soybean (Glycine max), is an important and valuable field crop. Thus, acontinuing goal of soybean plant breeding is to develop stable, highyielding soybean cultivars that are agronomically sound. The reasons forthis goal are to maximize the amount of grain produced on the land usedand to supply food for both animals and humans. To accomplish this goal,the soybean breeder must select and develop soybean plants that have thetraits that result in superior varieties.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated, and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report,” Iowa Soybean Promotion Board and AmericanSoybean Association Special Report 92S (May 1990)). Changes in fattyacid composition for improved oxidative stability and nutrition areconstantly sought after. Industrial uses of soybean oil, which issubjected to further processing, include ingredients for paints,plastics, fibers, detergents, cosmetics, lubricants, and biodiesel fuel.Soybean oil may be split, inter-esterified, sulfurized, epoxidized,polymerized, ethoxylated, or cleaved. Designing and producing soybeanoil derivatives with improved functionality and improved oliochemistryis a rapidly growing field. The typical mixture of triglycerides isusually split and separated into pure fatty acids, which are thencombined with petroleum-derived alcohols or acids, nitrogen, sulfonates,chlorine, or with fatty alcohols derived from fats and oils to producethe desired type of oil or fat.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for poultry, swine, andcattle feed. During processing of whole soybeans, the fibrous hull isremoved and the oil is extracted. The remaining soybean meal is acombination of carbohydrates and approximately 50% protein.

For human consumption, soybean meal is made into soybean flour, which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats, aswell as dairy type products.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

FURTHER EMBODIMENTS OF THE INVENTION

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, which are introduced into the genome using transformation orvarious breeding methods are referred to herein collectively as“transgenes.” In some embodiments of the invention, a transgenic variantof soybean cultivar 02340134 may contain at least one transgene butcould contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and/or no morethan 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2. Over the last 15to 20 years several methods for producing transgenic plants have beendeveloped, and the present invention also relates to transgenic variantsof the claimed soybean cultivar 02340134.

Nucleic acids or polynucleotides refer to RNA or DNA that is linear orbranched, single or double stranded, or a hybrid thereof. The term alsoencompasses RNA/DNA hybrids. These terms also encompass untranslatedsequence located at both the 3′ and 5′ ends of the coding region of thegene: at least approximately 1000 nucleotides of sequence upstream fromthe 5′ end of the coding region and at least approximately 200nucleotides of sequence downstream from the 3′ end of the coding regionof the gene. Less common bases, such as inosine, 5-methylcytosine,6-methyladenine, hypoxanthine and others can also be used for antisense,dsRNA and ribozyme pairing. For example, polynucleotides that containC-5 propyne analogues of uridine and cytidine have been shown to bindRNA with high affinity and to be potent antisense inhibitors of geneexpression. Other modifications, such as modification to thephosphodiester backbone, or the 2′-hydroxy in the ribose sugar group ofthe RNA can also be made. The antisense polynucleotides and ribozymescan consist entirely of ribonucleotides, or can contain mixedribonucleotides and deoxyribonucleotides. The polynucleotides of theinvention may be produced by any means, including genomic preparations,cDNA preparations, in vitro synthesis, RT-PCR, and in vitro or in vivotranscription.

One embodiment of the invention is a process for producing soybeancultivar 02340134 further comprising a desired trait, said processcomprising introducing a transgene that confers a desired trait to asoybean plant of cultivar 02340134. Another embodiment is the productproduced by this process. In one embodiment the desired trait may be oneor more of herbicide resistance, insect resistance, disease resistance,decreased phytate, or modified fatty acid or carbohydrate metabolism.The specific gene may be any known in the art or listed herein,including: a polynucleotide conferring resistance to imidazolinone,dicamba, sulfonylurea, glyphosate, glufosinate, triazine, benzonitrile,cyclohexanedione, phenoxy propionic acid, and L-phosphinothricin; apolynucleotide encoding a Bacillus thuringiensis polypeptide; apolynucleotide encoding phytase, FAD-2, FAD-3, galactinol synthase, or araffinose synthetic enzyme; or a polynucleotide conferring resistance tosoybean cyst nematode, brown stem rot, Phytophthora root rot, soybeanmosaic virus, or sudden death syndrome.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993), andArmstrong, “The First Decade of Maize Transformation: A Review andFuture Perspective,” Maydica, 44:101-109 (1999). In addition, expressionvectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation,” in Methodsin Plant Molecular Biology and Biotechnology, Glick and Thompson Eds.,CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothercultivar using traditional breeding techniques that are well known inthe plant breeding arts. For example, a backcrossing approach iscommonly used to move a transgene from a transformed soybean cultivarinto an already developed soybean cultivar, and the resulting backcrossconversion plant would then comprise the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to, genes,coding sequences, inducible, constitutive and tissue specific promoters,enhancing sequences, and signal and targeting sequences. For example,see the traits, genes, and transformation methods listed in U.S. Pat.No. 6,118,055.

Included among various plant transformation techniques are methods thatpermit the site-specific modification of a plant genome, includingcoding sequences, regulatory elements, non-coding and other DNAsequences in a plant genome. Such methods are well-known in the art andinclude, for example, use of the CRISPR-Cas system, zinc-fingernucleases (ZFNs), and transcription activator-like effector nucleases(TALENs), among others.

Plant transformation may involve the construction of an expressionvector which will function in plant cells. Such a vector can compriseDNA comprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). The expression vector maycontain one or more such operably linked gene/regulatory elementcombinations. The vector(s) may be in the form of a plasmid and can beused alone or in combination with other plasmids to provide transformedsoybean plants using transformation methods as described below toincorporate transgenes into the genetic material of the soybeanplant(s).

Expression Vectors for Soybean Transformation: Marker Genes

Expression vectors include at least one genetic marker operably linkedto a regulatory element (for example, a promoter) that allowstransformed cells containing the marker to be either recovered bynegative selection, i.e., inhibiting growth of cells that do not containthe selectable marker gene, or by positive selection, i.e., screeningfor the product encoded by the genetic marker. Many commonly usedselectable marker genes for plant transformation are well known in thetransformation arts, and include, for example, genes that code forenzymes that metabolically detoxify a selective chemical agent which maybe an antibiotic or an herbicide, or genes that encode an altered targetwhich is insensitive to the inhibitor. A few positive selection methodsare also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983). Anothercommonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford et al., PlantPhysiol., 86:1216 (1988); Jones et al., Mol. Gen. Genet., 210:86 (1987);Svab et al., Plant Mol. Biol., 14:197 (1990); Hille et al., Plant Mol.Biol., 7:171 (1986)). Other selectable marker genes confer resistance toherbicides such as glyphosate, glufosinate, or bromoxynil (Comai et al.,Nature, 317:741-744 (1985); Gordon-Kamm et al., Plant Cell, 2:603-618(1990); Stalke et al., Science, 242:419-423 (1988)).

Selectable marker genes for plant transformation not of bacterial origininclude, for example, mouse dihydrofolate reductase, plant5-enolpyruvylshikimate-3-phosphate synthase, and plant acetolactatesynthase (Eichholtz et al., Somatic Cell Mol. Genet., 13:67 (1987); Shahet al., Science, 233:478 (1986); Charest et al., Plant Cell Rep., 8:643(1990)).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells, rather than directgenetic selection of transformed cells, for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include 0-glucuronidase (GUS),0-galactosidase, luciferase, and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri et al.,EMBO J., 8:343 (1989); Koncz et al., Proc. Natl. Acad. Sci. USA, 84:131(1987); DeBlock et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available (Molecular Probes, Publication2908, IMAGENE GREEN, pp. 1-4 (1993); Naleway et al., J. Cell Biol.,115:151a (1991)). However, these in vivo methods for visualizing GUSactivity have not proven useful for recovery of transformed cellsbecause of low sensitivity, high fluorescent backgrounds, andlimitations associated with the use of luciferase genes as selectablemarkers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells (Chalfie et al., Science, 263:802 (1994)). GFP and mutants of GFPmay be used as screenable markers.

Expression Vectors for Soybean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element (for example, a promoter).Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred.”Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific.” A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may affect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell-type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to agene for expression in soybean. Optionally, the inducible promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean. With aninducible promoter the rate of transcription increases in response to aninducing agent.

Any inducible promoter can be used in the instant invention. See, Wardet al., Plant Mol. Biol., 22:361-366 (1993). Exemplary induciblepromoters include, but are not limited to, that from the ACEI systemwhich responds to copper (Mett et al., Proc. Natl. Acad. Sci. USA,90:4567-4571 (1993)); In2 gene from maize which responds tobenzenesulfonamide herbicide safeners (Hershey et al., Mol. GenGenetics, 227:229-237 (1991); Gatz et al., Mol. Gen. Genetics, 243:32-38(1994)); or Tet repressor from Tn10 (Gatz et al., Mol. Gen. Genetics,227:229-237 (1991)). A particularly preferred inducible promoter is apromoter that responds to an inducing agent to which plants do notnormally respond. An exemplary inducible promoter is the induciblepromoter from a steroid hormone gene, glucocorticoid response elements,the transcriptional activity of which is induced by a glucocorticoidhormone (Schena et al., Proc. Natl. Acad. Sci. USA, 88:10421-10425(1991)).

B. Constitutive Promoters—A constitutive promoter is operably linked toa gene for expression in soybean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean.

Many different constitutive promoters can be utilized in the instantinvention. Exemplary constitutive promoters include, but are not limitedto, the promoters from plant viruses such as the 35S promoter from CaMV(Odell et al., Nature, 313:810-812 (1985)) and the promoters from suchgenes as rice actin (McElroy et al., Plant Cell, 2: 163-171 (1990));ubiquitin (Christensen et al., Plant Mol. Biol., 12:619-632 (1989);Christensen et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU (Last etal., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten et al., EMBOJ., 3:2723-2730 (1984)); and maize H3 histone (Lepetit et al., Mol. Gen.Genetics, 231:276-285 (1992); Atanassova et al., Plant Journal, 2 (3):291-300 (1992)). The ALS promoter, an Xba1/Ncol fragment 5′ to theBrassica napus ALS3 structural gene (or a nucleotide sequence similarityto said Xba1/Ncol fragment), represents a particularly usefulconstitutive promoter. See PCT Application WO 96/30530.

C. Tissue-Specific or Tissue-Preferred Promoters—A tissue-specificpromoter is operably linked to a gene for expression in soybean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in soybean. Plants transformed with a gene ofinterest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in theinstant invention. Exemplary tissue-specific or tissue-preferredpromoters include, but are not limited to, a root-preferred promotersuch as that from the phaseolin gene (Murai et al., Science, 23:476-482(1983); Sengupta-Gopalan et al., Proc. Natl. Acad. Sci. USA,82:3320-3324 (1985)); a leaf-specific and light-induced promoter such asthat from cab or rubisco (Simpson et al., EMBO J., 4(11):2723-2729(1985); Timko et al., Nature, 318:579-582 (1985)); an anther-specificpromoter such as that from LAT52 (Twell et al., Mol. Gen. Genetics,217:240-245 (1989)); a pollen-specific promoter such as that from Zm13(Guerrero et al., Mol. Gen. Genetics, 244:161-168 (1993)); or amicrospore-preferred promoter such as that from apg (Twell et al., Sex.Plant Reprod., 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of a protein produced by transgenes to a subcellularcompartment, such as the chloroplast, vacuole, peroxisome, glyoxysome,cell wall, or mitochondrion, or for secretion into the apoplast, isaccomplished by means of operably linking the nucleotide sequenceencoding a signal sequence to the 5′ and/or 3′ region of a gene encodingthe protein of interest. Targeting sequences at the 5′ and/or 3′ end ofthe structural gene may determine during protein synthesis andprocessing where the encoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker et al., Plant Mol. Biol., 20:49 (1992); Knox, C. et al.,Plant Mol. Biol., 9:3-17 (1987); Lerner et al., Plant Physiol.,91:124-129 (1989); Frontes et al., Plant Cell, 3:483-496 (1991);Matsuoka et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould et al., J.Cell. Biol., 108:1657 (1989); Creissen et al., Plant J., 2:129 (1991);Kalderon et al., Cell, 39:499-509 (1984); Steifel et al., Plant Cell,2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein can then beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6(1981).

According to a preferred embodiment, the transgenic plant provided forcommercial production of foreign protein is a soybean plant. In anotherpreferred embodiment, the biomass of interest is seed. For therelatively small number of transgenic plants that show higher levels ofexpression, a genetic map can be generated, primarily via conventionalRFLP, PCR, and SSR analysis, which identifies the approximatechromosomal location of the integrated DNA molecule. For exemplarymethodologies in this regard, see, Glick and Thompson, Methods in PlantMolecular Biology and Biotechnology, CRC Press, Inc., Boca Raton,269:284 (1993). Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant.

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome,” Science,280:1077-1082 (1998), and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, and sequencing, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of soybean, the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic, grain quality, and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to soybean, as well as non-nativeDNA sequences, can be transformed into soybean and used to alter levelsof native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.Reduction of the activity of specific genes (also known as genesilencing or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including, but not limited to, knock-outs (such as by insertion ofa transposable element such as mu (Vicki Chandler, The Maize Handbook,Ch. 118 (Springer-Verlag 1994)) or other genetic elements such as a FRTand Lox that are used for site specific integrations, antisensetechnology (see, e.g., Sheehy et al., PNAS USA, 85:8805-8809 (1988); andU.S. Pat. Nos. 5,107,065, 5,453,566, and 5,759,829); co-suppression(e.g., Taylor, Plant Cell, 9:1245 (1997); Jorgensen, Trends Biotech.,8(12):340-344 (1990); Flavell, PNAS USA, 91:3490-3496 (1994); Finneganet al., Bio/Technology, 12:883-888 (1994); Neuhuber et al., Mol. Gen.Genet., 244:230-241 (1994)); RNA interference (Napoli et al., PlantCell, 2:279-289 (1990); U.S. Pat. No. 5,034,323; Sharp, Genes Dev.,13:139-141 (1999); Zamore et al., Cell, 101:25-33 (2000); Montgomery etal., PNAS USA, 95:15502-15507 (1998)), virus-induced gene silencing(Burton et al., Plant Cell, 12:691-705 (2000); Baulcombe, Curr. Op.Plant Bio., 2:109-113 (1999)); target-RNA-specific ribozymes (Haseloffet al., Nature, 334: 585-591 (1988)); hairpin structures (Smith et al.,Nature, 407:319-320 (2000); WO 99/53050; WO 98/53083); MicroRNA(Aukerman & Sakai, Plant Cell, 15:2730-2741 (2003)); ribozymes(Steinecke et al., EMBO J., 11:1525 (1992); Perriman et al., AntisenseRes. Dev., 3:253 (1993)); oligonucleotide mediated targeted modification(e.g., WO 03/076574 and WO 99/25853); Zn-finger targeted molecules(e.g., WO 01/52620, WO 03/048345, and WO 00/42219); and other methods orcombinations of the above methods known to those of skill in the art.

The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are resistant to theseherbicides are described in U.S. Pat. Nos. 6,288,306, 6,282,837,5,767,373, and International Publication WO 01/12825.

Any of the above listed herbicide genes (A-E) can be introduced into theclaimed soybean cultivar through a variety of means including but notlimited to transformation and crossing.

3. Genes that Confer or Contribute to a Value-Added Trait, Such as:

A. Modified fatty acid metabolism, for example, by transforming a plantwith an antisense gene of stearyl-ACP desaturase to increase stearicacid content of the plant. See, Knultzon et al., Proc. Natl. Acad. Sci.USA, 89:2625 (1992).

B. Decreased phytate content: 1) Introduction of a phytase-encoding geneenhances breakdown of phytate, adding more free phosphate to thetransformed plant. For example, see, Van Hartingsveldt et al., Gene,127:87 (1993), for a disclosure of the nucleotide sequence of anAspergillus niger phytase gene. 2) Up-regulation of a gene that reducesphytate content. In maize, this, for example, could be accomplished bycloning and then re-introducing DNA associated with one or more of thealleles, such as the LPA alleles, identified in maize mutantscharacterized by low levels of phytic acid, such as in Raboy et al.,Maydica, 35:383 (1990), and/or by altering inositol kinase activity asin WO 02/059324, U.S. Publ. No. 2003/000901, WO 03/027243, U.S. Publ.No. 2003/0079247, WO 99/05298, U.S. Pat. Nos. 6,197,561, 6,291,224,6,391,348, WO 2002/059324, U.S. Publ. No. 2003/0079247, WO 98/45448, WO99/55882, and WO 01/04147.

C. Modified carbohydrate composition effected, for example, bytransforming plants with a gene coding for an enzyme that alters thebranching pattern of starch, or a gene altering thioredoxin, such as NTRand/or TRX (see, U.S. Pat. No. 6,531,648, which is incorporated byreference for this purpose), and/or a gamma zein knock out or mutant,such as cs27 or TUSC27 or en27 (see, U.S. Pat. Nos. 6,858,778 and7,741,533 and U.S. Publ. No. 2005/0160488, which are incorporated byreference for this purpose). See, Shiroza et al., J. Bacteriol., 170:810(1988) (nucleotide sequence of Streptococcus mutans fructosyltransferasegene); Steinmetz et al., Mol. Gen. Genet., 200:220 (1985) (nucleotidesequence of Bacillus subtilis levansucrase gene); Pen et al.,Bio/Technology, 10:292 (1992) (production of transgenic plants thatexpress Bacillus licheniformis alpha-amylase); Elliot et al., PlantMolec. Biol., 21:515 (1993) (nucleotide sequences of tomato invertasegenes); Sogaard et al., J. Biol. Chem., 268:22480 (1993) (site-directedmutagenesis of barley alpha-amylase gene); Fisher et al., PlantPhysiol., 102:1045 (1993) (maize endosperm starch branching enzyme II);WO 99/10498 (improved digestibility and/or starch extraction throughmodification of UDP-D-xylose 4-epimerase, Fragile 1 and 2, Ref 1, HCHL,C4H); U.S. Pat. No. 6,232,529 (method of producing high oil seed bymodification of starch levels (AGP)). The fatty acid modification genesmentioned above may also be used to affect starch content and/orcomposition through the interrelationship of the starch and oilpathways.

D. Elevated oleic acid via FAD-2 gene modification and/or decreasedlinolenic acid via FAD-3 gene modification. See, U.S. Pat. Nos.6,063,947, 6,323,392, and International Publication WO 93/11245.Linolenic acid is one of the five most abundant fatty acids in soybeanseeds. The low oxidative stability of linolenic acid is one reason thatsoybean oil undergoes partial hydrogenation. When partiallyhydrogenated, all unsaturated fatty acids form trans fats. Soybeans arethe largest source of edible-oils in the U.S. and 40% of soybean oilproduction is partially hydrogenated. The consumption of trans fatsincreases the risk of heart disease. Regulations banning trans fats haveencouraged the development of low linolenic soybeans. Soybeanscontaining low linolenic acid percentages create a more stable oilrequiring hydrogenation less often. This provides trans-fat freealternatives in products such as cooking oil.

E. Altering conjugated linolenic or linoleic acid content, such as in WO01/12800. Altering LEC1, AGP, Dek1, Superal1, mi1ps, and various Ipagenes, such as Ipa1, Ipa3, hpt, or hggt. See, for example, WO 02/42424,WO 98/22604, WO 03/011015, WO 02/057439, WO 03/011015, U.S. Pat. Nos.6,423,886, 6,197,561, 6,825,397, 7,157,621, U.S. Publ. No. 2003/0079247,and Rivera-Madrid, R. et al., Proc. Natl. Acad. Sci., 92:5620-5624(1995).

F. Altered antioxidant content or composition, such as alteration oftocopherol or tocotrienols. See, for example, U.S. Pat. Nos. 6,787,683,7,154,029, WO 00/68393 (involving the manipulation of antioxidant levelsthrough alteration of a phytl prenyl transferase (ppt)); WO 03/082899(through alteration of a homogentisate geranyl geranyl transferase(hggt)).

G. Altered essential seed amino acids. See, for example, U.S. Pat. No.6,127,600 (method of increasing accumulation of essential amino acids inseeds); U.S. Pat.

4. Genes that Control Male Sterility:

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on,”the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

This includes the introduction of FRT sites that may be used in theFLP/FRT system and/or Lox sites that may be used in the Cre/loxP system.See, for example, Lyznik et al., Site-Specific Recombination for GeneticEngineering in Plants, Plant Cell Rep, 21:925-932 (2003) and WO99/25821, which are hereby incorporated by reference.

For example,see: WO 00/73475 where water use efficiency is altered throughalteration of malate; U.S. Pat. Nos. 5,892,009, 5,965,705, 5,929,305,5,891,859, 6,417,428, 6,664,446, 6,706,866, 6,717,034, 6,801,104, WO2000/060089, WO 2001/026459, WO 2001/035725, WO 2001/034726, WO2001/035727, WO 2001/036444, WO 2001/036597, WO 2001/036598, WO2002/015675, WO 2002/017430, WO 2002/077185, WO 2002/079403, WO2003/013227, WO 2003/013228, WO 2003/014327, WO 2004/031349, WO2004/076638, WO 98/09521, and WO 99/38977 describing genes, includingCBF genes and transcription factors effective in mitigating the negativeeffects of freezing, high salinity, and drought on plants, as well asconferring other positive effects on plant phenotype; U.S. Publ.

Methods for Soybean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). Inaddition, expression vectors and in-vitro culture methods for plant cellor tissue transformation and regeneration of plants are available. See,for example, Gruber et al., “Vectors for Plant Transformation,” inMethods in Plant Molecular Biology and Biotechnology, Glick and ThompsonEds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation—One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch et al., Science,227:1229 (1985). A. tumefaciens and A. rhizogenes are plant pathogenicsoil bacteria which genetically transform plant cells. The Ti and Riplasmids of A. tumefaciens and A. rhizogenes, respectively, carry genesresponsible for genetic transformation of the plant. See, for example,Kado, C. I., Crit. Rev. Plant Sci., 10:1 (1991). Descriptions ofAgrobacterium vector systems and methods for Agrobacterium-mediated genetransfer are provided by Gruber et al., supra, Miki et al., supra, andMoloney et al., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat.No. 5,563,055 (Townsend and Thomas), issued Oct. 8, 1996.

B. Direct Gene Transfer—Several methods of plant transformation,collectively referred to as direct gene transfer, have been developed asan alternative to Agrobacterium-mediated transformation. A generallyapplicable method of plant transformation is microprojectile-mediatedtransformation where DNA is carried on the surface of microprojectilesmeasuring 1 to 4 m. The expression vector is introduced into planttissues with a biolistic device that accelerates the microprojectiles tospeeds of 300 to 600 m/s which is sufficient to penetrate plant cellwalls and membranes. Sanford et al., Part. Sci. Technol., 5:27 (1987);Sanford, J. C., Trends Biotech., 6:299 (1988); Klein et al., Bio/Tech.,6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein etal., Biotechnology, 10:268 (1992). See also, U.S. Pat. No. 5,015,580(Christou et al.), issued May 14, 1991 and U.S. Pat. No. 5,322,783(Tomes et al.), issued Jun. 21, 1994.

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang et al., Bio/Technology, 9:996 (1991). Alternatively,liposome and spheroplast fusion have been used to introduce expressionvectors into plants. Deshayes et al., EMBO J., 4:2731 (1985); Christouet al., Proc Natl. Acad. Sci. USA, 84:3962 (1987). Direct uptake of DNAinto protoplasts using CaCl₂) precipitation, polyvinyl alcohol orpoly-L-ornithine have also been reported. Hain et al., Mol. Gen. Genet.,199:161 (1985) and Draper et al., Plant Cell Physiol., 23:451 (1982).Electroporation of protoplasts and whole cells and tissues have alsobeen described (Donn et al., In Abstracts of VII^(th) InternationalCongress on Plant Cell and Tissue Culture IAPTC, A2-38, p. 53 (1990);D'Halluin et al., Plant Cell, 4:1495-1505 (1992); and Spencer et al.,Plant Mol. Biol., 24:51-61 (1994)).

Following transformation of soybean target tissues, expression of theabove-described selectable marker genes allows for preferentialselection of transformed cells, tissues, and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic cultivar. The transgenic cultivar could then becrossed with another (non-transformed or transformed) cultivar in orderto produce a new transgenic cultivar. Alternatively, a genetic traitthat has been engineered into a particular soybean line using theforegoing transformation techniques could be moved into another lineusing traditional backcrossing techniques that are well known in theplant breeding arts. For example, a backcrossing approach could be usedto move an engineered trait from a public, non-elite cultivar into anelite cultivar, or from a cultivar containing a foreign gene in itsgenome into a cultivar or cultivars that do not contain that gene. Asused herein, “crossing” can refer to a simple x by y cross or theprocess of backcrossing depending on the context.

Genetic Marker Profile Through SSR and First Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same cultivar,or a related cultivar, or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) (which are also referred to asMicrosatellites), and Single Nucleotide Polymorphisms (SNPs). Forexample, see, Cregan et al., “An Integrated Genetic Linkage Map of theSoybean Genome,” Crop Science, 39:1464-1490 (1999) and Berry et al.,“Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Inbred Lines and Soybean Varieties,”Genetics, 165:331-342 (2003), each of which are incorporated byreference herein in their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forsoybean cultivar 02340134.

Primers and PCR protocols for assaying these and other markers aredisclosed in the Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University). In addition to being used foridentification of soybean cultivar 02340134, and plant parts and plantcells of soybean cultivar 02340134, the genetic profile may be used toidentify a soybean plant produced through the use of soybean cultivar02340134 or to verify a pedigree for progeny plants produced through theuse of soybean cultivar 02340134. The genetic marker profile is alsouseful in breeding and developing backcross conversions.

The present invention provides in one embodiment a soybean plantcultivar characterized by molecular and physiological data obtained fromthe representative sample of said cultivar deposited with theProvasoli-Guillard National Center for Marine Algae and Microbiota(NCMA). Further provided by the invention is a soybean plant formed bythe combination of the disclosed soybean plant or plant cell withanother soybean plant or cell and comprising the homozygous alleles ofthe cultivar.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, bypolymerase chain reaction (PCR), thereby eliminating the need forlabor-intensive Southern hybridization. PCR detection is done by use oftwo oligonucleotide primers flanking the polymorphic segment ofrepetitive DNA. Repeated cycles of heat denaturation of the DNA followedby annealing of the primers to their complementary sequences at lowtemperatures, and extension of the annealed primers with DNA polymerase,comprise the major part of the methodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties it is preferable if all SSRprofiles are performed in the same lab.

Primers used are publicly available and may be found in the Soybase orCregan supra. See also, PCT Publication No. WO 99/31964 (NucleotidePolymorphisms in Soybean); U.S. Pat. No. 6,162,967 (Positional Cloningof Soybean Cyst Nematode Resistance Genes); and U.S. Pat. No. 7,288,386(Soybean Sudden Death Syndrome Resistant Soybeans and Methods ofBreeding and Identifying Resistant Plants), the disclosure of which areincorporated herein by reference.

The SSR profile of soybean plant 02340134 can be used to identify plantscomprising soybean cultivar 02340134 as a parent, since such plants willcomprise the same homozygous alleles as soybean cultivar 02340134.Because the soybean cultivar is essentially homozygous at all relevantloci, most loci should have only one type of allele present. Incontrast, a genetic marker profile of an F₁ progeny should be the sum ofthose parents, e.g., if one parent was homozygous for allele x at aparticular locus, and the other parent homozygous for allele y at thatlocus, then the F₁ progeny will be xy (heterozygous) at that locus.Subsequent generations of progeny produced by selection and breeding areexpected to be of genotype x (homozygous), y (homozygous), or xy(heterozygous) for that locus position. When the F₁ plant is selfed orsibbed for successive filial generations, the locus should be either xor y for that position.

In addition, plants and plant parts substantially benefiting from theuse of soybean cultivar 02340134 in their development, such as soybeancultivar 02340134 comprising a backcross conversion, transgene, orgenetic sterility factor, may be identified by having a molecular markerprofile with a high percent identity to soybean cultivar 02340134. Sucha percent identity might be 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9%identical to soybean cultivar 02340134.

The SSR profile of soybean cultivar 02340134 can also be used toidentify essentially derived varieties and other progeny varietiesdeveloped from the use of soybean cultivar 02340134, as well as cellsand other plant parts thereof. Such plants may be developed using themarkers identified in WO 00/31964, U.S. Pat. Nos. 6,162,967, and7,288,386. Progeny plants and plant parts produced using soybeancultivar 02340134 may be identified by having a molecular marker profileof at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 76%,77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%,91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% geneticcontribution from soybean cultivar, as measured by either percentidentity or percent similarity. Such progeny may be furthercharacterized as being within a pedigree distance of soybean cultivar02340134, such as within 1, 2, 3, 4, or 5 or less cross-pollinations toa soybean plant other than soybean cultivar 02340134 or a plant that hassoybean cultivar 02340134 as a progenitor. Unique molecular profiles maybe identified with other molecular tools such as SNPs and RFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant cultivar, an F₁ progeny produced from such cultivar, and progenyproduced from such cultivar.

Single-Gene Conversions

When the term “soybean plant” is used in the context of the presentinvention, this also includes any single gene conversions of thatcultivar. The term single gene converted plant as used herein refers tothose soybean plants which are developed by a plant breeding techniquecalled backcrossing wherein essentially all of the morphological andphysiological characteristics of a cultivar are recovered in addition tothe single gene transferred into the cultivar via the backcrossingtechnique. By “essentially all” as used herein in the context ofmorphological and physiological characteristics it is meant that thecharacteristics of a plant are recovered that are otherwise present whencompared in the same environment, other than occasional variant traitsthat might arise during backcrossing or direct introduction of atransgene. It is understood that a locus introduced by backcrossing mayor may not be transgenic in origin, and thus the term backcrossingspecifically includes backcrossing to introduce loci that were createdby genetic transformation.

Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the cultivar. The term “backcrossing”as used herein refers to the repeated crossing of a hybrid progeny backto the recurrent parent, i.e., backcrossing 1, 2, 3, 4, 5, 6, 7, 8, ormore times to the recurrent parent. The parental soybean plant thatcontributes the gene for the desired characteristic is termed thenonrecurrent or donor parent. This terminology refers to the fact thatthe nonrecurrent parent is used one time in the backcross protocol andtherefore does not recur. The parental soybean plant to which the geneor genes from the nonrecurrent parent are transferred is known as therecurrent parent as it is used for several rounds in the backcrossingprotocol (Poehlman & Sleper (1994); Fehr, Principles of CultivarDevelopment, pp. 261-286 (1987)). In a typical backcross protocol, theoriginal cultivar of interest (recurrent parent) is crossed to a secondcultivar (nonrecurrent parent) that carries the single gene of interestto be transferred. The resulting progeny from this cross are thencrossed again to the recurrent parent and the process is repeated untila soybean plant is obtained wherein essentially all of the morphologicaland physiological characteristics of the recurrent parent are recoveredin the converted plant, in addition to the single transferred gene fromthe nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalcultivar. To accomplish this, a single gene of the recurrent cultivar ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the genetic, andtherefore the morphological and physiological constitution of theoriginal cultivar. The choice of the particular nonrecurrent parent willdepend on the purpose of the backcross; one of the major purposes is toadd some agronomically important trait to the plant. The exactbackcrossing protocol will depend on the characteristic or trait beingaltered to determine an appropriate testing protocol. Althoughbackcrossing methods are simplified when the characteristic beingtransferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new cultivar but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic. Examples of these traits include, but are not limited to,male sterility, waxy starch, herbicide resistance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability, andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185, 5,973,234, and 5,977,445, the disclosures of which arespecifically hereby incorporated by reference.

Introduction of a New Trait or Locus into Soybean Cultivar 02340134

Cultivar 02340134 represents a new base genetic cultivar into which anew locus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression. The term backcross conversion andsingle locus conversion are used interchangeably to designate theproduct of a backcrossing program.

Backcross Conversions of Soybean Cultivar 02340134

A backcross conversion of soybean cultivar 02340134 occurs when DNAsequences are introduced through backcrossing (Hallauer et al., “CornBreeding,” Corn and Corn Improvements, No. 18, pp. 463-481 (1988)), withsoybean cultivar 02340134 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a trait or locus conversion in at least two or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses, and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,see, Openshaw, S. J. et al., Marker-assisted Selection in BackcrossBreeding, Proceedings Symposium of the Analysis of Molecular Data, CropScience Society of America, Corvallis, Oreg. (August 1994), where it isdemonstrated that a backcross conversion can be made in as few as twobackcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes ascompared to unlinked genes), the level of expression of the trait, thetype of inheritance (cytoplasmic or nuclear), and the types of parentsincluded in the cross. It is understood by those of ordinary skill inthe art that for single gene traits that are relatively easy toclassify, the backcross method is effective and relatively easy tomanage. (See, Hallauer et al., Corn and Corn Improvement, Sprague andDudley, Third Ed. (1998)). Desired traits that may be transferredthrough backcross conversion include, but are not limited to, sterility(nuclear and cytoplasmic), fertility restoration, nutritionalenhancements, drought tolerance, nitrogen utilization, altered fattyacid profile, low phytate, industrial enhancements, disease resistance(bacterial, fungal, or viral), insect resistance, and herbicideresistance. In addition, an introgression site itself, such as an FRTsite, Lox site, or other site specific integration site, may be insertedby backcrossing and utilized for direct insertion of one or more genesof interest into a specific plant cultivar. A single locus may containseveral transgenes, such as a transgene for disease resistance that, inthe same expression vector, also contains a transgene for herbicideresistance. The gene for herbicide resistance may be used as aselectable marker and/or as a phenotypic trait. A single locusconversion of site specific integration system allows for theintegration of multiple genes at the converted loci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman, Breeding Field Crops,p. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant, and easily recognized traits.

One process for adding or modifying a trait or locus in soybean cultivar02340134 comprises crossing soybean cultivar 02340134 plants grown fromsoybean cultivar 02340134 seed with plants of another soybean cultivarthat comprise the desired trait or locus, selecting F₁ progeny plantsthat comprise the desired trait or locus to produce selected F₁ progenyplants, crossing the selected progeny plants with the soybean cultivar02340134 plants to produce backcross progeny plants, selecting forbackcross progeny plants that have the desired trait or locus and themorphological characteristics of soybean cultivar 02340134 to produceselected backcross progeny plants, and backcrossing to soybean cultivar02340134 three or more times in succession to produce selected fourth orhigher backcross progeny plants that comprise said trait or locus. Themodified soybean cultivar 02340134 may be further characterized ashaving the morphological and physiological characteristics of soybeancultivar 02340134 listed in Table 1 as determined at the 5% significancelevel when grown in the same environmental conditions and/or may becharacterized by percent similarity or identity to soybean cultivar02340134 as determined by SSR markers. The above method may be utilizedwith fewer backcrosses in appropriate situations, such as when the donorparent is highly related or markers are used in the selection step.Desired traits that may be used include those nucleic acids known in theart, some of which are listed herein, that will affect traits throughnucleic acid expression or inhibition. Desired loci include theintrogression of FRT, Lox, and other sites for site specificintegration, which may also affect a desired trait if a functionalnucleic acid is inserted at the integration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing soybeancultivar 02340134 with the introgressed trait or locus with a differentsoybean plant and harvesting the resultant first generation progenysoybean seed.

Tissue Culture

Further reproduction of the cultivar can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well known and widely published. Forexample, reference may be had to Komatsuda, T. et al., Crop Sci.,31:333-337 (1991); Stephens, P. A. et al., Theor. Appl. Genet.,82:633-635 (1991); Komatsuda, T. et al., Plant Cell, Tissue and OrganCulture, 28:103-113 (1992); Dhir, S. et al., Plant Cell Reports,11:285-289 (1992); Pandey, P. et al., Japan J. Breed., 42:1-5 (1992);and Shetty, K. et al., Plant Science, 81:245-251 (1992); as well as U.S.Pat. No. 5,024,944, issued Jun. 18, 1991 to Collins et al. and U.S. Pat.No. 5,008,200, issued Apr. 16, 1991 to Ranch et al. Thus, another aspectof this invention is to provide cells which upon growth anddifferentiation produce soybean plants having the morphological andphysiological characteristics of soybean cultivar 02340134.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods,petioles, leaves, stems, roots, root tips, anthers, pistils, and thelike. Means for preparing and maintaining plant tissue culture are wellknown in the art. By way of example, a tissue culture comprising organshas been used to produce regenerated plants. U.S. Pat. Nos. 5,959,185,5,973,234, and 5,977,445 describe certain techniques, the disclosures ofwhich are incorporated herein by reference.

Using Soybean Cultivar 02340134 to Develop Other Soybean Varieties

Soybean varieties such as soybean cultivar 02340134 are typicallydeveloped for use in seed and grain production. However, soybeanvarieties such as soybean cultivar 02340134 also provide a source ofbreeding material that may be used to develop new soybean varieties.Plant breeding techniques known in the art and used in a soybean plantbreeding program include, but are not limited to, recurrent selection,bulk selection, mass selection, backcrossing, pedigree breeding, openpollination breeding, restriction fragment length polymorphism enhancedselection, genetic marker enhanced selection, making double haploids,and transformation. Often combinations of these techniques are used. Thedevelopment of soybean varieties in a plant breeding program requires,in general, the development and evaluation of homozygous varieties.There are many analytical methods available to evaluate a new cultivar.The oldest and most traditional method of analysis is the observation ofphenotypic traits, but genotypic analysis may also be used.

Additional Breeding Methods

This invention is directed to methods for producing a soybean plant bycrossing a first parent soybean plant with a second parent soybean plantwherein either the first or second parent soybean plant is cultivar02340134. The other parent may be any other soybean plant, such as asoybean plant that is part of a synthetic or natural population. Anysuch methods using soybean cultivar 02340134 are part of this invention:selfing, sibbing, backcrosses, mass selection, pedigree breeding, bulkselection, hybrid production, crosses to populations, and the like.These methods are well known in the art and some of the more commonlyused breeding methods are described below. Descriptions of breedingmethods can be found in one of several reference books (e.g., Allard,Principles of Plant Breeding (1960); Simmonds, Principles of CropImprovement (1979); Sneep et al. (1979); Fehr, “Breeding Methods forCultivar Development,” Chapter 7, Soybean Improvement, Production andUses, 2nd ed., Wilcox editor (1987)).

The following describes breeding methods that may be used with soybeancultivar 02340134 in the development of further soybean plants. One suchembodiment is a method for developing a cultivar 02340134 progenysoybean plant in a soybean plant breeding program comprising: obtainingthe soybean plant, or a part thereof, of cultivar 02340134, utilizingsaid plant, or plant part, as a source of breeding material, andselecting a soybean cultivar 02340134 progeny plant with molecularmarkers in common with cultivar 02340134 and/or with morphologicaland/or physiological characteristics selected from the characteristicslisted in Tables 1 or 2. Breeding steps that may be used in the soybeanplant breeding program include pedigree breeding, backcrossing, mutationbreeding, and recurrent selection. In conjunction with these steps,techniques such as RFLP-enhanced selection, genetic marker enhancedselection (for example, SSR markers), and the making of double haploidsmay be utilized.

Another method involves producing a population of soybean cultivar02340134 progeny soybean plants, comprising crossing cultivar 02340134with another soybean plant, thereby producing a population of soybeanplants which, on average, derive 50% of their alleles from soybeancultivar 02340134. A plant of this population may be selected andrepeatedly selfed or sibbed with a soybean cultivar resulting from thesesuccessive filial generations. One embodiment of this invention is thesoybean cultivar produced by this method and that has obtained at least50% of its alleles from soybean cultivar 02340134.

One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see, Fehr and Walt, Principles of CultivarDevelopment, pp. 261-286 (1987). Thus the invention includes soybeancultivar 02340134 progeny soybean plants comprising a combination of atleast two cultivar 02340134 traits selected from the group consisting ofthose listed in Tables 1 and 2 or the cultivar 02340134 combination oftraits listed in the Summary of the Invention, so that said progenysoybean plant is not significantly different for said traits thansoybean cultivar 02340134 as determined at the 5% significance levelwhen grown in the same environmental conditions. Using techniquesdescribed herein, molecular markers may be used to identify said progenyplant as a soybean cultivar 02340134 progeny plant. Mean trait valuesmay be used to determine whether trait differences are significant, andpreferably the traits are measured on plants grown under the sameenvironmental conditions. Once such a cultivar is developed, its valueis substantial since it is important to advance the germplasm base as awhole in order to maintain or improve traits such as yield, diseaseresistance, pest resistance, and plant performance in extremeenvironmental conditions.

Progeny of soybean cultivar 02340134 may also be characterized throughtheir filial relationship with soybean cultivar 02340134, as forexample, being within a certain number of breeding crosses of soybeancultivar 02340134. A breeding cross is a cross made to introduce newgenetics into the progeny, and is distinguished from a cross, such as aself or a sib cross, made to select among existing genetic alleles. Thelower the number of breeding crosses in the pedigree, the closer therelationship between soybean cultivar 02340134 and its progeny. Forexample, progeny produced by the methods described herein may be within1, 2, 3, 4, or 5 breeding crosses of soybean cultivar 02340134.

As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cell tissue cultures from which soybean plants can beregenerated, plant calli, plant clumps, and plant cells that are intactin plants or parts of plants, such as embryos, pollen, ovules, flowers,pods, leaves, roots, root tips, anthers, cotyledons, hypocotyls,meristematic cells, stems, pistils, petiole, and the like.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such assoybean cultivar 02340134 and another soybean cultivar having one ormore desirable characteristics that is lacking or which complementssoybean cultivar 02340134. If the two original parents do not provideall the desired characteristics, other sources can be included in thebreeding population. In the pedigree method, superior plants are selfedand selected in successive filial generations. In the succeeding filialgenerations, the heterozygous condition gives way to homogeneousvarieties as a result of self-pollination and selection. Typically inthe pedigree method of breeding, five or more successive filialgenerations of selfing and selection is practiced: F₁ to F₂; F₂ to F₃;F₃ to F₄; F₄ to F₅; etc. After a sufficient amount of inbreeding,successive filial generations will serve to increase seed of thedeveloped cultivar. Preferably, the developed cultivar compriseshomozygous alleles at about 95% or more of its loci.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one cultivar, the donor parent, to adeveloped cultivar called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent, but at the same time retain manycomponents of the nonrecurrent parent by stopping the backcrossing at anearly stage and proceeding with selfing and selection. For example, asoybean cultivar may be crossed with another cultivar to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC₁ or BC₂.Progeny are selfed and selected so that the newly developed cultivar hasmany of the attributes of the recurrent parent and yet several of thedesired attributes of the nonrecurrent parent. This approach leveragesthe value and strengths of the recurrent parent for use in new soybeanvarieties.

Therefore, an embodiment of this invention is a method of making abackcross conversion of soybean cultivar 02340134, comprising the stepsof crossing a plant of soybean cultivar 02340134 with a donor plantcomprising a desired trait, selecting an F₁ progeny plant comprising thedesired trait, and backcrossing the selected F₁ progeny plant to a plantof soybean cultivar 02340134. This method may further comprise the stepof obtaining a molecular marker profile of soybean cultivar 02340134 andusing the molecular marker profile to select for a progeny plant withthe desired trait and the molecular marker profile of soybean cultivar02340134. In one embodiment, the desired trait is a mutant gene ortransgene present in the donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Soybean cultivar 02340134 is suitablefor use in a recurrent selection program. The method entails individualplants cross pollinating with each other to form progeny. The progenyare grown and the superior progeny selected by any number of selectionmethods, which include individual plant, half-sib progeny, full-sibprogeny, and selfed progeny. The selected progeny are cross pollinatedwith each other to form progeny for another population. This populationis planted and again superior plants are selected to cross pollinatewith each other. Recurrent selection is a cyclical process and thereforecan be repeated as many times as desired. The objective of recurrentselection is to improve the traits of a population. The improvedpopulation can then be used as a source of breeding material to obtainnew varieties for commercial or breeding use, including the productionof a synthetic cultivar. A synthetic cultivar is the resultant progenyformed by the intercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self-pollination, directed pollinationcould be used as part of the breeding program.

Mutation Breeding

Mutation breeding is another method of introducing new traits intosoybean cultivar 02340134. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.,cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil)), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in Fehr,“Principles of Cultivar Development,” Macmillan Publishing Company(1993). In addition, mutations created in other soybean plants may beused to produce a backcross conversion of soybean cultivar 02340134 thatcomprises such mutation.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs), and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing soybean cultivar 02340134.

Isozyme Electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, Molecular Linkage Map ofSoybean (Glycine max L. Merr.), pp. 6.131-6.138 (1993). In S. J. O'Brien(ed.), Genetic Maps: Locus Maps of Complex Genomes, Cold Spring HarborLaboratory Press, Cold Spring Harbor, N.Y., developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD, 3 classical markers, and 4 isozyme loci. See also,Shoemaker, R. C., 1994 RFLP Map of Soybean, pp. 299-309; In R. L.Phillips and I. K. Vasil (ed.), DNA-based markers in plants, KluwerAcademic Press Dordrecht, the Netherlands.

SSR technology is currently the most efficient and practical markertechnology. More marker loci can be routinely used, and more alleles permarker locus can be found, using SSRs in comparison to RFLPs. Forexample, Diwan and Cregan described a highly polymorphic microsatelliteloci in soybean with as many as 26 alleles. (Diwan, N. and Cregan. P.B., Automated sizing of fluorescent-labelled simple sequence repeat(SSR) markers to assay genetic variation in Soybean, Theor. Appl.Genet., 95:220-225 (1997). Single Nucleotide Polymorphisms may also beused to identify the unique genetic composition of the invention andprogeny varieties retaining that unique genetic composition. Variousmolecular marker techniques may be used in combination to enhanceoverall resolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan et al., “An Integrated Genetic Linkage Map of the SoybeanGenome,” Crop Science, 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean, as well as the most current genetic map, may befound in Soybase on the World Wide Web.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.Molecular markers may also be used to identify and exclude certainsources of germplasm as parental varieties or ancestors of a plant byproviding a means of tracking genetic profiles through crosses.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which soybean cultivar 02340134 is a parentcan be used to produce double haploid plants. Double haploids areproduced by the doubling of a set of chromosomes (1 N) from aheterozygous plant to produce a completely homozygous individual. Forexample, see, Wan et al., “Efficient Production of Doubled HaploidPlants Through Colchicine Treatment of Anther-Derived Maize Callus,”Theoretical and Applied Genetics, 77:889-892 (1989) and U.S. Pat. No.7,135,615. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, Am. Nat., 93:381-382 (1959); Sharkar and Coe, Genetics,54:453-464 (1966); KEMS (Deimling, Roeber, and Geiger, Vortr.Pflanzenzuchtg, 38:203-224 (1997); or KMS and ZMS (Chalyk, Bylich &Chebotar, MNL, 68:47 (1994); Chalyk & Chebotar, Plant Breeding,119:363-364 (2000)); and indeterminate gametophyte (ig) mutation(Kermicle, Science, 166:1422-1424 (1969). The disclosures of which areincorporated herein by reference.

Methods for obtaining haploid plants are also disclosed in Kobayashi, M.et al., Journ. of Heredity, 71(1):9-14 (1980); Pollacsek, M., Agronomie(Paris) 12(3):247-251 (1992); Cho-Un-Haing et al., Journ. of PlantBiol., 39(3):185-188 (1996); Verdoodt, L. et al., 96(2):294-300(February 1998); Genetic Manipulation in Plant Breeding, ProceedingsInternational Symposium Organized by EUCARPIA, Berlin, Germany (Sep.8-13, 1985); Chalyk et al., Maize Genet Coop., Newsletter 68:47 (1994).

Thus, an embodiment of this invention is a process for making asubstantially homozygous soybean cultivar 02340134 progeny plant byproducing or obtaining a seed from the cross of soybean cultivar02340134 and another soybean plant and applying double haploid methodsto the F₁ seed or F₁ plant or to any successive filial generation. Basedon studies in maize and currently being conducted in soybean, suchmethods would decrease the number of generations required to produce acultivar with similar genetics or characteristics to soybean cultivar02340134. See, Bernardo, R. and Kahler, A. L., Theor. Appl. Genet.,102:986-992 (2001).

In particular, a process of making seed retaining the molecular markerprofile of soybean cultivar 02340134 is contemplated, such processcomprising obtaining or producing F₁ seed for which soybean cultivar02340134 is a parent, inducing doubled haploids to create progenywithout the occurrence of meiotic segregation, obtaining the molecularmarker profile of soybean cultivar 02340134, and selecting progeny thatretain the molecular marker profile of soybean cultivar 02340134.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard (1960); Simmonds (1979); Sneep et al. (1979); Fehr(1987)).

Industrial Uses

The seed of soybean cultivar 02340134, the plant produced from the seed,the hybrid soybean plant produced from the crossing of the cultivar withany other soybean plant, hybrid seed, and various parts of the hybridsoybean plant can be utilized for human food, livestock feed, and as araw material in industry. The soybean seeds produced by soybean cultivar02340134 can be crushed, or a component of the soybean seeds can beextracted, in order to comprise a commodity plant product, such asprotein concentrate, protein isolate, soybean hulls, meal, flour, or oilfor a food or feed product.

Soybean cultivar 02340134 can be used to produce soybean oil. To producesoybean oil, the soybeans harvested from soybean cultivar 02340134 arecracked, adjusted for moisture content, rolled into flakes and the oilis solvent-extracted from the flakes with commercial hexane. The oil isthen refined, blended for different applications, and sometimeshydrogenated. Soybean oils, both liquid and partially hydrogenated, areused domestically and exported, sold as “vegetable oil” or are used in awide variety of processed foods.

Soybean cultivar 02340134 can be used to produce meal. After oil isextracted from whole soybeans harvested from soybean cultivar 02340134,the remaining material or “meal” is “toasted” (a misnomer because theheat treatment is with moist steam) and ground in a hammer mill. Soybeanmeal is an essential element of the American production method ofgrowing farm animals, such as poultry and swine, on an industrial scalethat began in the 1930s; and more recently the aquaculture of catfish.Ninety-eight percent of the U.S. soybean crop is used for livestockfeed. Soybean meal is also used in lower end dog foods. Soybean mealproduced from soybean cultivar 02340134 can also be used to producesoybean protein concentrate and soybean protein isolate.

In addition to soybean meal, soybean cultivar 02340134 can be used toproduce soy flour. Soy flour refers to defatted soybeans where specialcare was taken during desolventizing (not toasted) to minimizedenaturation of the protein and to retain a high Nitrogen SolubilityIndex (NSI) in making the flour. Soy flour is the starting material forproduction of soy concentrate and soy protein isolate. Defatted soyflour is obtained from solvent extracted flakes, and contains less than1% oil. Full-fat soy flour is made from unextracted, dehulled beans, andcontains about 18% to 20% oil. Due to its high oil content, aspecialized Alpine Fine Impact Mill must be used for grinding ratherthan the more common hammer mill. Low-fat soy flour is made by addingback some oil to defatted soy flour. The lipid content varies accordingto specifications, usually between 4.5% and 9%. High-fat soy flour canalso be produced by adding back soybean oil to defatted flour at thelevel of 15%. Lecithinated soy flour is made by adding soybean lecithinto defatted, low-fat or high-fat soy flours to increase theirdispersibility and impart emulsifying properties. The lecithin contentvaries up to 15%.

For human consumption, soybean cultivar 02340134 can be used to produceedible protein ingredients which offer a healthier, less expensivereplacement for animal protein in meats, as well as in dairy-typeproducts. The soybeans produced by soybean cultivar 02340134 can beprocessed to produce a texture and appearance similar to many otherfoods. For example, soybeans are the primary ingredient in many dairyproduct substitutes (e.g., soy milk, margarine, soy ice cream, soyyogurt, soy cheese, and soy cream cheese) and meat substitutes (e.g.,veggie burgers). These substitutes are readily available in mostsupermarkets. Although soy milk does not naturally contain significantamounts of digestible calcium (the high calcium content of soybeans isbound to the insoluble constituents and remains in the soy pulp), manymanufacturers of soy milk sell calcium-enriched products as well. Soy isalso used in tempeh: the beans (sometimes mixed with grain) arefermented into a solid cake.

Additionally, soybean cultivar 02340134 can be used to produce varioustypes of “fillers” in meat and poultry products. Food service, retail,and institutional (primarily school lunch and correctional) facilitiesregularly use such “extended” products, that is, products which containsoy fillers. Extension may result in diminished flavor, but fat andcholesterol are reduced by adding soy fillers to certain products.Vitamin and mineral fortification can be used to make soy productsnutritionally equivalent to animal protein; the protein quality isalready roughly equivalent.
